How to program an nRF51822 using SWDIO/CLK?

[Oliver]

Hej,

that might sound like a dumb question, but what is the minimal setup to program an nRF51822 SoC using the SWDIO/CLK ports?

1. What external hardware is required?
2. What software is required to built and flash a new firmware?
   • What about the mbed SDK? Can I use it with a minimal setup?

I'm essentially looking for a minimal setup, which allows me to power and flash an nRF51822 based installation.

Sincerely, Oliver

A further note on SWD code... I wrote my own because I had some special requirements, but there is a library called libswd (Google will find) which might do this for you.

For minimal-in-terms-of hardware, it is hard to beat that FTDI solution.

I mean for the nRF51822. Something like the minimal layout presented in the datasheet put on a tiny breakout board. For the programmer, and also for the chip, I would prefer an assembled and working unit. Hassle free, but minimal. Seems like I'm failing in getting my point across :/

There's an onboard programmer on the nRF51 Dongle as well. So you don't need an additional one. If you do however we use the tools from Segger J-link. The nRF51-DK (PCA10028) is capable of programming external boards as well. So if you want to have one board to develop on to be able to program your own custom boards in the future, that would be the one to recommend.

Hello Asbjorn ...i have nRF51-DK(PCA10028) and i want to program my own board which is based on NRF51822 .. i connect debug out header P19 to my board . can you please tell me what is the requirement that i full fill . and is any change that i want to make.? and if i load code in NnRF board than it automatically load in my board or not?
